Four stroke options

[James Lee]

I just picked up an IT250 81 roller,will the front end and swing arm/shock fit my XT250?
Im thinking of my next 4 stroke project already.

WOW,what a nice macine,looks like you have put some hours into that one.What shocks are those?

Thanks. Yep, there were more hours put into it than I care to think about. And I wont even think about how many spondoolies it soaked up. Still, it was a labour of love and it was a bit cheaper than a C&J. The shocks are Ohlins painted in Honda colours.

Ohlins as fitted to twin shock Huskys etc in early 80's

Front end will fit but swingarm/shock won't, 78 YZ250/400 swingarm will but shocks are too long best to fit a custom shock from works performance etc.

OK thanks.

I'm thinking of fitting my XT250 engine into the 81 IT250 chassis,any know problems?I think it would make a great bike.

Annard and Thompson did a xt 250 with IT suspension back in 81 or 82, I have a T&T article on it somewhere, from what I remember it was an easy conversion, I'll see if I can chase it up. It would be much easier to upgrade the XT suspension than putting the motor in another frame..

That would be great evo550.I'm going to see how the suspenion fits up over the next couple of days.I'm going to build a full fleat of 4 stroke MX bikes out of stuff I have lying around.My XR600 will be ready for the track soon,just had worn dogs on 2nd and 5th gears so just waiting on parts.My SP370 is hauling now with some jet and needle changes,its a great bike,just need to sort some decent shocks.

[evo550]

I'll chase it up over the weekend.

Can anyone please help me out with some shocks for my SP?Id like to ride it more but my shocks are completly blown out.something in the 365mm range or a bit longer will work for me.

I saw several sets of Works Performance shocks that length or perhaps 370-375mm on ebay this morning.

Gazi has that length   http://www.gazisuspension.com/

Gazi only show road bike application from what I can see....  with only 100mm of shaft travel. 

[LWC82PE]

Yeah that's not good. On the SP or any other bike that has the shock mount back near the axle you need to have a shock with as much shaft travel as possible to get a decent wheel travel because of the lever ratio.

[Slakewell]

These work fine on my husky to give 250mm of legal pre 78 travel
