How to calculate new chain length after sprocket change

It'll be like trying to ride a Gasgas but with fuck loads of weight and a really high seat.

Fucking stupid idea.

Bajaj were pretty poor at making Vespas, which had decades of ‘reliability’ behind them.
The 125 dukes have a nylon oil drive pinion that poops itself, resulting in a knackered big end.
This engine is on my bench. In bits.

If the 390 is better built, I cannot say. I can say, however, Bajaj.

The very best of luck to you.

For downgeared fun, get a front sprocket with one or two less teeth than standard and a rear sprocket with 3 or 4 more teeth.

Whats the price range.

You can just grab a DRZ400 for fucking around on, crashing them costs pennies to fix and are readily available, not 'super' by any stretch, but a good way in to fucking around on a bike. If you are going to downgear, even a Honda FMX650 whilst woefully shit, would wheelie all day every day with a dinner plate sprocket.

I wouldn't say a Hornet is good at all, most revvy 6s make power above the first half of the rev range which means big sprocket to make it come lower down/get more oomph for your rev in the low range, but its still a Hornet thats got better road purposes.

Unless you are dreadfully serious about stunting, might be worth a day or two at a stunt place, you'll be knackered within an hour and fall off more than you care to believe, at which point you will reconsider.

Don't see many stunters for sale either, guessing because the 50+ drops in a month and smashed in tanks devalues it enough to write it off Laughing

If you really wanted a bike to troll on, my track SV650 is sitting unused, road reg'd, hasn't run for a few years after I moved, but buying a non-road legal bike would probs be your best bet and just fucking it that way... wouldnt buy a perfectly good road bike to downgear beyond belief.

Most bikes are around 1:2.5 sprocket ratio but if you go for stunt gearing the wrap is much further around as Katy said.

Who needs EFI, DRZ400s are pretty low tune and can be given a decent bump with an FCR39 and a 3x3 mod.

For £2500-3000 they arent bad, but they aren't as quick as you'de expect and would get a better rear shock

I'm going to view a DR Z400 SM today. I don't really know what to expect. I've never a ridden a single over 125cc before. Is there anything I should look out for regarding this particular model? Anything that might seem ominous to me but would be normal for this bike? i.e. I'm used to riding fairly newer bikes, would something like a clunky gearbox or a noisy engine or anything like that, which might otherwise put me off, be normal for this bike? Likewise, any issues regarding this particular model to look out for that might otherwise go unnoticed?

Can you find a cheaper one? There's a private sale for £3k in Wales but this is only an hour away from me. They go from £3k to like £5k+. I think they are quite rare and sought after these days???

Check it’s not stolen, because most of them have been.

Thanks. It's been HPI checked by the trader (although I have to be honest I didn't bother to cast my over it Embarassed

) so I would sincerely hope not!

Looking through the paperwork and can't actually find any HPI paperwork so I think I'll go online now and get one done for £2.99 just for peace of mind...

I took it away. Managed to get £95 knocked off the price. Not fantastic but better than nothing.

Riding it home all seemed fine until I got onto the motorway and it seemed to be randomly and intermittently lurching/juddering while cruising at 70mph. Admittedly I did after a while realise I hadn't managed to knock it up into 5th gear (wasn't counting the gears as I went up and was pretty sure I had gone up as far as I could go as a few attempts wasn't going up any further) and once I had realised and got it up into 5th it did seem a lot better but not 100% Hitting the rev limit perhaps? I think not though because it seemed quite random and not always at a certain speed as you would expect when you hit the limiter. 78mph (indicated) is all I could hit in 4th gear but 5th gear released another 8 to 10mph on top of that.

Normal for a 16 year old bike? Maybe the carbs need some attention? Sold without warranty which I'm not sure they're allowed to do, I thought 3 months was statutory? Sales invoice simply states warranty: none. No mention of it being sold as seen, a non-runner, for parts, spares or repair or scrap or any of that old guff.

Ok...

It has outstanding finance.

Suggestions?

Bury head and hope for the best?

Contact the trader?

Contact the finance company listed on the report?

I wouldn't trust a dealer's HPI check at all - always do your own checks..

I looked at Astra a few years ago from a used car place down the road from me, dealer showed HPI all clear. Went ahead and bought it. Couple of years later went to trade it in at a main dealer, and couldn't as they showed outstanding finance owed on it from the previous owner. Took me ages to get it sorted with the finance company as the bloke I'd bought it off went out of business literally 2 weeks after I bought the car. Fortunately it was a low value car and they just wrote off the finance and cleared it.

My Triumph was showing as outstanding finance when I bought it, even after 3 months despite me paying off the actual finance on the phone at point of collection. Same as my Benelli too, it should come.off pretty quick, but yes worth chasing the dealer to double check, they may have paid it off and you are in the same situation as me and it's just finance folk being slow.

DRZ are holding money right now, but it's why I won't go to a dealer to buy one. Their premium ruins the bargain part of buying.

Statutory obligation to a 3 month warranty? Confused

TravisBickle · World Chat Champion Joined: 17 May 2019 Karma :

Yeah.

Or did I just imagine that?

I thought there was a legal thing that traders can't back out of. It's not like purchasing an extended warranty, it's like any trader has to provide a 3 month warranty on any vehicle they sell whether they disclose that at the point of sale or not (which 99.9% of the time they don't).

Pretty sure that's in law.

Or did I just make that up?
