I'm looking for a motorcycle streamliner project or possibly a turnkey bike. I prefer under 500cc but will consider a larger bike depending on the builder. It doesn't need to have bodywork, but that would be nice.
I'm a tall guy so the frame should be able to be modified.
Best regards

I've been told by a reliable source the Vincent has stability problems.

That goes hand in hand with a bikeliner but I had wondered if the big Vincent's had given it a high CG. CG, CP & steering inputs can all contribute to instability & are all correctable. A smaller engine & some low ballast will likely make it a whole different animal.

Jim, your reliable source may not be that reliable... by definition, bike liners are hard to ride, but I know 2 guys that got in and rode that one with no previous bike liner experience.... in fact they alternated turns and kept it up on its wheels for a couple of years, only riding once a year.  It was converted to a sidecar liner, but not because it had stability issues...

 Someone stating the stability of a Bike Liner would just about be the most personal subjective opinion I could imagine.

I like kiwi belly tank's answer. He offered sound advice for solving any problems with a streamliner. Buying a streamliner is a serious purchase, that could get somebody hurt. So a buyer should hear the good and bad about buying anything. Loyalty to friends is wonderful, but opinions based on friendships shouldn't interfere with disclosing possible problems. I know people that are following the Vincent and trust Max. I have tried to contact Max about his bike and haven't gotten a response. I haven't totally written it off as a possible purchase, I just want more information that includes the good and bad, because I can fix the bad, if I know about it.
Best regards

Jim you may have luck contacting Max through Facebook. He is more active on there than he seems to be on here. Could be worth a try.
My understanding was the Vincent liner had a 3rd wheel added solely for the purpose of aiming for a different record. The liner always seemed stable to me from talking to Donny and Hartmutt (the 2 pilots in more recent years, since about 2005 I think).

Good luck with your hunt for a liner.

I sent this thread to Max.  Hopefully he will reply soon.

First MC streamliner I saw run was Don Vesco in 1970 and I recall he did ~250 on its side!  :-o :-o

While it is true that we had all sorts of mechanical problems and desasters happen during my 10 years with the Lambky liner, my handling problems were few. I rode the thing on full steering lock through the lights due to heavy side wind, had a rear wheel explode at around 175, a locked up engine spun the liner around so that I was going backwards but the only time I layed it on its side was when I took my first driving lesson (accidently I pulled the skids in at standstill). Max tried several different set-ups for the rear end but the last creation was the best. The aerodynamics are very slippery as well so with a good engine package the thing should go very well. The potential for the Vincent liner was in the region of 350mph, one year I was about to change into top gear and had it up to around 6000 in second, that was about 250mph - the thing was rocksteady and did not need my input - sadly the blowershaft broke and sidelined us. Due to bad weather and other circumstances beyond our control I never got another chance to go 300.
