That's an impressive bike you've got there mate, and I bet that'll be fun to ride over winter
I have seen a RD350 engine in an old lambretta before which to be honest is a scary thought, that looks like a lot of fun though.
Has the engine had any tuning work (I don't know what the usual power output of the RZ350 is?).
Cheers

Very impressive bike!!!
Although, personally I'd have shoved in a 4 stroke 250 or 400 if the frame could take it  |

Something that occurred to me, is what do they do with all those acres of space between the tank and the engine? Air cooling? Or just leave a huge gap because there isn't anything to go there?
Or perhaps, they just use the extra space created by the small horizontal 2t engines to put in a massive fuel tank. It's not as if they don't need all the fuel they can get.  ____________________ I must not be a troll...

I would use that big space to store my bacon butties and a flask.
pack them in there before you leave and whenever the call of hunger or thirst kicks in your all geared up  |

Very cool Well done that lunatic
Looks like a nice snug fit must have taken a while to build.
I bet that front wheel never touches the floor with 70bhp at the rear,should suprise a few people when a 125 comes flying past them  ____________________ Nothing gets the point across quite like a raised middle digit.

very nice, very neat! That Mito chassis looks like it was made for the YPVS! Im doing a college night class on MC maintainence/workshop, and one of the Tutors has 2 LC350's one heavily modded with KR1 wheels, forks, and clocks, JMC rear end, and a YPVS motor.
Has anybody seen last months streetfighters magazine? It has a KMX400 supermoto bike, using a GSXR400 engine, in a modified frame. It looks brilliant, and has got me thinking if i could get a bigger engine in mine, though i very much doubt il ever do it, as im going to spend a fair amount on the std 200cc unit, and get some decent power out of that. I think a CRM250/RMX250 engine with autolube might slot in easy enough though. |

It is a 5 year older design of engine making basically the same power as the RGV / RS. The hot 250s didn't manage to get near its power until the RGV / KR1 came out, with the original TZR250 managing 45hp, and the RG250 stuggling to get over 40. Was quite a common conversion to build a YammaGamma, sticking the RD350YPVS engine into an RG250 chassis.
The RD was also a fairly good bike to use with a pillion, and quite useable at low revs.
From memory the F1 version of the power valve was the best basis for tuning as the ignition system was better at high revs. The later F2 wasn't so good.
All the best

Yeah but a 60bhp YPVS engine will run long after a 60bhp KR1/RGV has gone pop. The extra capacity for similar power give the 350YPVS a reliability advantage. Added to that is the fact there are about 5-6 Re-bore sizes should it wear out or seize up, and its a far better prospect. The KR1's need careful building and blueprinting to last, and the RGV self destructs taking out the cylinders and probably the cran and rods, if you dont replace all the top end parts before they start wearing out. A blow up on either of these will cost loads more to sort than an RD350 motor would. 2 new or re-plated cylinders every time?
The liners in the RD also have enough metal in them to allow a 375cc overbore, and im sure ive heard of RD's running at 398cc also. a good std one should make 50bhp at the back wheel, 59bhp at the crank, but a 62bhp RGV still only makes usually 53bhp at the wheel, and it has alot less torque, and no midrange compared to the RD. 60bhp at the wheel from an RD is an easy tune, and 70bhp is still reasonable in reliability. The motor can go alot further than that though with expensive TZ350 parts, and 85bhp is quite possible then.
As for the BDK RGV500 its not as close a GP500 experience as Mark Dents RGV570, his makes at least another 10bhp and weighs about 130kg roughly. It's still got an RG chassis though, so its handling is limited, who with an engine like that who the hell cares! |
