montesaman Posted May 8, 2007 Report Share Posted May 8, 2007 Hello TY gurus, I think I saw a thread on this a year or two ago - just wondering whether anyone knew if it is possible to convert a 250R to a 350 like the had over in the states? What would it involve- can you get the parts across the pond?, what they're like even (would I want to? ) When I had them back in the day I think the only common capacity increase was to 270. Any idea how much this would cost now? Also, I remember some of the keen lads converting to a rear disc, were they any good? are there any latter disc kits that may fit of other bikes?

biffsgasgas Posted May 16, 2007 Report Share Posted May 16, 2007 If you are thinking of a ty 350 yamaha then carb jetting, Reed block with different stops, and a jug is all that is needed. I ciezed a pinky 250 when i was a kid doing something stupid the day before an event and swapped over all of the above from my 86 ty 350. The fly wheel is also different but i liked the rev of the 250 flywheel. The head fit from the 250 on the 350 head. If your talking about a 350 honda..... I dont know of one in the states. --Biff Quote Link to comment Share on other sites More sharing options...
