Hi guys I know I'm new to the forum just couldn't find a newbie section so I thought I would dive straight in to the workshop section. I'm from South Wales and have been riding around 2 years now.

I brought a Yamaha XT125R 2006 model just under 2 years ago (will be 2 years in February) ever since I've had it it's been problem after problem. Had snapped clutch and throttle cables, collapsed wheel bearings, fork legs split, the list is endless.
Last Monday I hit a cow I took my bike to JT's in Swansea and got them to carry out the work as there a registered yamaha dealer. Was told it wouldn't be ready until sometime next week as they would need to order parts from Holland, I got the phone call yesterday telling me it was ready to pick up.
Here's where it starts I picked it up and before I even started it I noticed brake fluid leaking from the front break lever area, I immediately got someone to sort it out and some guy come out and tightened the banjo. I pulled out of the car park and instantly realised they hadn't had the handle bars off or even straightened the front end I continued home because it was a job I could do myself and just wanted to get back, half way home the bolts fell out of the exhaust I called them up in disgust and raised the issue of the front end still being bent. He told me on the job card they had straightened as much as possible I instantly told them I wasn't happy I could straighten it myself and was convinced they had done something to the exhaust. I hang up in rage and noticed there was a haldfords opposite me I spent £13 and fixed it on my own in the car park and continued the ride home.
I was riding to work this morning and got half way and my engine just sounded like it was throttling back like it was running out of petrol the it just cut out and sounded like something was slapping around in the engine. Do any of you guys think they could of done something ? I know I hit a cow but not that hard, I haven't got a clue who's at fault I'm thinking them because that's a lot to go wrong straight after having it back off them. But I know what there going to say "prove it" so I started stripping it down and took the carb off and in the inlet manifold there is fine silver fillings, anyone have a clue as to what that is?
How hard is it to replace a barrel, piston etc. I'm quite mechanically minded just I gave them the bike because that's who the insurance wanted me to take it to well a yamaha approved dealer and they were the closest. Thanks guys and will be looking forward to your reply's

Damn that's some bad luck there.... unfortunately I'd have said that since you have been messing around with it then it'll be very difficult to prove it was the shop that done any damage.

As for fitting the piston and barrel, having a quick look at the bike, it looks simple enough, I'd expect someone with very little mechanical knowledge to have that done in a couple of hours.

Oh and watch out for animals in the road in future Wink

Insurance? You notified them?

Why have they not fixed it then? If you aren't claiming, they shouldn't really give a flying fuck where it goes.

How much oil is actually in your engine, do you check it daily?

Yeah I notified them because was told repairs would be £400 + and with Christmas approaching £300 was my limit. Just something else I now have to pay out for -_-
I have been mistreated in putting a BBR 150 kit on been told it's better acceleration and all round better kit what do you guys think?
I check my oil weekly I know it should be daily but don't always have the chance as like now I'm just leaving to go to work. Thanks guys

We talking like a 150cc kit?

That is opening a whole can of worms if so....

Notifying the DVLA of engine capacity change..
Insuring it as a modified vehicle..
Are you licenced to drive such a vehicle - if you are on L's then no.

Sounds like Yam are letting their QC slip. My old 1998 SR125 had none of the problems that your 2006 XT does.

With the millage I do (80/100 a day) I need a reliable kit I'm sick off the bike breaking down all the time, I'm prepared to risk driving it on L's with a 150cc bore kit

Fair play, but the 150 kit will probs be less reliable then genuine Yam parts. Chances are the 150 kit comes of a shitty chinese production line and the engineering/materials selection isn't near that of OEM Yam stuff.

The older XTs more or less shared an engine with the SR125, which was dead simple to work and and never skipped a beat. I don't know if the newer XT125R's are the same but it wouldn't surprise me.

If you are after reliability, definitely stick with OEM parts. The whole bike will have been designed with the stock engine in mind, the clutch, gears, bottom end etc etc. You might be able to run slightly higher power and eat a little into the safety factor but if reliability is your goal, then I'd avoid.

What sort of riding are you doing that puts 80 miles a day on a 125? That's pretty hard going.

From what I can understand the BBR kit is made of better quality it's made in America with precision engineering it's built to high standards and there very confident in there work. They have lots of performance parts to tag along with it like specially made exhaust and CDI units for higher revving. Lightened flywheels etc. Google the kits and the company and also people have fitted them on XT's on this forum I believe.
I drive to and from work everyday with a 50 mile round trip then everyday drive to my girlfriends that's a 30/40 mile round trip depending on what direction I'm coming from then spinning and going to the shops on top of all that. Been doing that for the past 12 months.

I did fairly similar mileage on a Varadero and here is the mileage...

That's through nothing but sensible oil changes and not ragging a cold engine. All engine parts are still the stock stuff the came with the bike.

The only reason your engine lunched itself is because you haven't looked after it.

Big bore = bad idea, it won't last as well as you think.

You'll also probably need more than just the top end.

Checking the oil is a 30 second job... just check it, start the bike, put your lid and gloves on while it is warming up then go, gently for a mile or 2.

I'm starting to smell a bit of cow shit here.

First claims to have hit a cow and had the repairs done by a main dealer, but mucks about with it on the way home, then strips the engine down to put in a bigger bore kit but claims it was the main dealer that's ruined his engine.

Thinking

It's not bullshit I know mechanically what I'm doing I've stripped this bike down many times just never gone into the engine besides changing clutch plates. I fixed it myself with a set if Allen keys from halfords on my way home because they wanted me to take the bike back and keep it there till Monday that was a 20 ish mile journey away and didn't have a lift back, I admit I don't look after it and rag the balls out of it even when cold just learnt my lesson the hard way and was only asking if it was possibly related to the garage because of the other problems when picking it up.

Maybe just cut your losses, buy the YBR engine that goes in there and just look after it.

So that makes it sound like they haven't done anything to to bike and you've fucked it up yourself... but trying to blame them anyway.

Short answer is no... you fucked it up yourself, either pay to have it sorted properly or fix it yourself

A replacement engine is £300 roughly without postage. Then I can't guarantee that the wiring is going to fit

Just compare wiring diagrams surely?

The charging system will in both cases be a permanent magnet alternator, I'm guessing 3-phase (altho some 125s are single), so that won't be a worry. Try to find out if the pickups for the ignition are the same, if the CDI is compatible.

If the wiring doesn't fit, swap any electronic xt parts for the ybr parts. Keep all the bits that are interchangeable.

You are doing 80 miles a day on a lightweight, and admit to thrashing it.... yeah, THAT ent likely to help it be a good reliable every day get to work motorcycle, is it?
Effing about with big bore kits... dont tell me, you reckon that its not so it'll go faster, but go 'as fast' with less stress... yeah, yeah... heard it all before!

What you want is to 'rant' and get sympathy and for us to agree that dealers are a bunch of rob-dog prats and that you have done a far better job and its all their fault, depriving you of your bent bike for a week, and doing sod all to it... but some-hoe in doing nothing, being to blame for a fucked engine and exhaust..

Ohh poor didums.

There you go... there's your sympathy.

Bastard rob dogs! How DARE they, waste your time and make your life hard, keeping your bike in thier workshop! CHARGING your insurance company for the privilidge!

Out RAGE iouse!

There you go... there the compasion with your rant....

NOW shall we take a step back into the real world?

Do you have a Full Licence?

If not, what the fuck you been doing for the last two years? First twelve months of them you could have, for grand sum of £121.50 tested on your XTR125 and got yourself a full ride what you like, but only 33bhp for two years licence, rather than suffer the heniouse must do das or be on a 125 for life system that came in this Jan just gone.

If you have a full licence.... 80 miles a day, ragging the shit out of a lightweight learner legal.... THIS IS WHAT HAPPENS! they get fucked.

Fixing the fucker ent going to solve the problem... just prolong it. You'll carry on ragging lightweight over high miles, till you fuck it again, and again and again.......

So, where does this take us?

You have fucked eight year old Learner-Legal... which by prices you have found would cost more to fix than its worth.... THAT we call 'Beyond Ecconomical Repair' or in the parlance Scrap Mi Bouyoh!

I would say dont have a cow... but think you already have.... who says welshmen dont like a bit of veriety in thier sex life! (couldn't resist)

Anyway; conclusion is that the thing is not worth fixing, at least not to 'factory' standard with New OE parts from Fowlers.

Cheap Chitty chinky bits might prove more promicing, BUT you are probably still looking at around £200's worth of bits, IF as I suspect the problem is basically extreme wear on hard worked little engine, done the last by being left on its side, when you fucked the cow.

Piston Rings & Rebore might be give or take as much as new barel; but, you have probably got rather chewed cam and or cam bearings in there as well... could get it running, on the cheap, but ent going to do the job you want.

So, to solve the REAL PROBLEM... you need a bike that CAN stand high daily miles, without being so stressed needing to be so thrashed to cover it in reasonable time....

To wit; obviouse answer is a 500 Commuter Twin or similar... WHICH without too much hunting ought to be available for little more money than you are talking for fixing the XT....

No Brainer to my mind.....

Wing and a prayer when will it brake bodged up XT125 and strain of thrashing it to do 40 miles to work.... OR I dont know? An £800 ER5 or similar... that even with A2 washers up its chuff delivers three and a half times the poke that the XT does, with or without the super-awsome extra a 150 big-bore probably doesn't offer.

Comfy, reliable, ecconomical, fast, powerful and and well, in so MANY ways just 'better' all round for almost everything you suggest you need.

All for the sake of taking a test... if you haven't done so.

THAT is where I would suggest you put your attension. Stop looking for XT parts and price up a new bike, and if needs, course to get licence to ride it.

When you have sorted THAT, then you might be able to recover something from the scrap thats your XT.

Sell as is 'Spares or Repairs' some optimist will give you hard cash for it as a non runner.

Bodge it back together, with whatever, and flog as a runner... you might get more money back gross than flogging SorR, though not my first choice.

Write it off; problem solved for less £ than fixing the XT... stick it in a skip.

Or something else... dont really matter.

Point is that thay bike is NOT the tool for the job, and you are, trying to flog a dead horse percevering with it.....

Although as you seem to like torturing ruminants, you may find that apealing.

BUT... thats the bottom line... its the wrong bike for the job; it hasn't done it; is unlikely to carry on barely doing it; and is just going to continue giving you grief and hassle.

Dealers? Forget it; another dead horse. They will suggest that straightening bent bike they have not touched the engine; thats down to you.... and it PROBABLY is.

There you go. I dont do sympathy and compasion; I do solve the problem, and in this case you are looking at the WRONG problem...

Its not that your bikes broke and needs fixing; its that its the wrong bike for the job, and THAT is why it broke.
