Ty 350 Conversion ?

Featured Replies

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?

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.
