Craving for a big bore

[firko]

I'd like to get a 250 Honda and turn it into a bigbore

Unfortunately the fly in the ointment is the gearbox. It can't handle the stock 250 so with a 360 kit it'd be doubtful you'd get through a days racing with third gear intact.
It's been done by a friend of mine twice (MT gearbox and stock box and different bore/stroke combos) with the same result both times. Heartache and an empty wallet.

An acquired taste - some love 'em, most hate 'em. Quirky handling for my money.

Thanks for the info - seems that I wrongly assumed that an M with its bigger casings etc would be at least as strong or stronger than the R's running around with mugen kits on them.

why the fixation on pre-75?
what sort of riding are you intending to do?
how much work are you prepared to devote to it?
how much money are you prepared to spend on it?

get any of them, and you have the usual triangle of FAST/GOOD/CHEAP - you only get two :-)
(if it is fast and good, it ain't going to be cheap)

Any 30-40 yr old MX bike is going to be fun to play with and ride.
Make your own choice and be bloody happy falling off the thing and grinning.

I have been after tm400 for ages If I only get one more bike that will be it for some it isn't about performance or handling your still going to have fun I just really like the thought of a over powered motor in a low slung frame with no suspension or brakes doesn't sound good but would be very fun hopefully I will get one sooner than later thanks Michael.

Agree with Luke,  there is a few questions to be asked,  Lukes questions,  then there is your budget?
Looks like you  have a favour for yamaha,  mX 360's are still around,  especially the imports,  then there is the odd SC500 pops up.  They are grunty and torquey if you tweek them,  but they will always have the irononing board frame,  so you wont be able to jump them far without bottoming out,  35 years, thats another type of riding,  great for grass track/TT Circuits.  But thats my recommendation.  MX 250/360 SC500.

Suzuki TM400?  I get a real kick out of finding out that, in 1974, I earned CMC Open Pro #8 on the most vicious, malevolent motorcycle ever produced, on the meanest and roughest track in world history: Carlsbad (and Saddleback).  It's fun to read historical stories about things we didn't realize back then. But to really appreciate what we are talking about, we need to hop into the "Wayback" machine.  In retrospect, was the TM400 hard to ride?  Yep, as were ALL Open Class bikes of the day.  It was faster, accelerated past anything else on the market, was cheap by comparison, dependable, and was as traditional in design as you could find for the time.  As with all MX bikes; even today's, the difference between winning and losing was more rider than machine; most especially back in those days.  Although I had mucho experience with CMC for over six years (raced virtually EVERY weekend), I knew that the 10% difference between motorcycles was less than the 20% difference in rider talent.  Hence, I saved money and bought a TM400.  It was all the critics said.  The throttle could have been replaced with a toggle switch, it handled kind of weird, everybody was afraid of it.  But I could win on it, perhaps for those very reasons.  I'm restoring one now, with NO intentions of riding it, or any other Open bike.  I'm 63 and will have plenty of fun on a 250; a TM250, by the way.  The Husky was too short, the CZ was too heavy, the Montesa was underpowered, and on and on.  There was always something wrong with every Open bike.  The bottom line was if you had the balls, or lack of brains, to get on one.  I won on that TM against the best CMC had.  Not always, but often enough.  For today?  They are easy to find, easy to restore, easy to find parts, they are supported by the aftermarket group, and they STILL take balls to ride.  But you CAN win.  Just use the same discretion and caution that you would apply to any other bike you would ride, and you will have fun.  Well, gotta go.  The pain medicine is starting to work and typing becomes a chore. Damn, I left my pills in the other room.  Check out www.motomanrules.com for pics of my latest project.
