after aquiring a kawasaki 250 ninja rolling chassis for peanuts, i decided it would make a perfect recipient for a suzuki 2 stroke engine. so the plan is: change the swingarm for a lighter alli gsx-r400 item, fabricate some frame tubes to make an engine cradle and fit the gt350 engine i built. standard gt250 engine going in THAT frame and sell it. this one might be a bit of a challenge, but at that price i couldn't resist :D
cheers, dd.
here's what i started with.

Looks interesting dd. Figuring a way to make the engine a stressed member and eliminate the down tubes would be cool though.

Cheers Geoff

Fascinating! Are you planning to leave it un-faired?

hi geoff, thanks for the input. i've looked at using the engine as a stressed member and doing away with an engine cradle - which is how the original engine was fitted - but the gt250 top end doesn't have many strong points to hang it from, i mean where? the holes for the ramair covers? very weak. the 2 holes next to the exhausts? the boss there is small, just big enough for a 6mm bolt, but not big enough for an m8, which i'd need [at least]. even a pair of brackets down to the front engine mount wouldn't work, as they are notorious for breaking, even in a gt250 frame, when ham fisted peeps overtighten the bolt through them. if you've got any ideas i haven't thought of, i'd be glad to at least consider them :D
sportston. i like my bikes like i like my women - naked :D i've never had a bike with a fairing on yet, i know the plus side to them, but for a special, why cover all the fabbing you've done with a fairing? :D thanks for the interest anyway.
cheers, dd.

Hi dd,

I was thinking of the T500 in a modern CB500 alu frame special that has popped up on the forum. I have no idea if the 250 engine could be approached the same way though.

I'm with you on having the engine on display though. To me it states MOTOR BIKE in the best way. I cringe at most modern "nakeds" with pipes and radiator stuff all over the place (and no bodywork to cover them up :D )

Cheers Geoff

hi geoff, what about you using a gsx-r400 rolling chassis? nice looking chassis and still suzuki :D i'm sure you'd get a t500 engine in there, with the added bonus of ali frame and swingarm, monoshock and usd forks. even those 3 spoke wheels with the curved 'spokes' look good. i've got a pair, all polished up and they look superb. unfortunately i don't have anything to use them on atm. also got the gsx-r400 swingarm, monoshock and dogbones. all doing nowt, if you're interested? i have got the frame, but no paperwork with it, i bought off a breaker to build a track day bike years ago, but never got round to it :D sure i've got a pair of usd forks as well somewhere, but they are definitely 600, not 400. if you feel like going mad, or you know somebody, just pm me and we can soon sort something :D
cheers, dd.

Hi dd,

Thanks for the offer but I have enough to do in the workshop with the bikes I have :D . It requires a fair bit of stamina to take a project from a bare chassis to a working bike and I don't have the resources at the moment.

Cheers Geoff

ok geoff, just a thought. didn't want you going down the h*nda route, when you could stay suzuki :D
got the 25mm square tubing today - 3mm wall x 7.5 metres long and less than £20 - cheap as chips :D
cheers, dd.

let battle commence.

change of plan, now that sundial has re-opened for business i had to post something :D
decided on round 27mm tube, same as gt250 front tubing, instead of the square tube. finding somebody to bend it to my specs is going to be the difficult bit. would really like them mandrel bent, but everybody i've phoned round here has said 'a what bend'? :D so it looks like an hydraulic bender. i'm not going the fill it with sand and heat it up method, far too much work, taking far too long. in theory two-thirds of winter over, soon be spring and fingers will be thawed out - can't wait :D
cheers, dd.
