just got a email and yes Dave has a head

[Ktm181]

thanks Shelp,

just sent Dave a message, cant get him to answer from an email address i have/had, shall see what he wants for it.....

What makes you want more out of an RM500? They made good power, easy to use which is THE most important thing on a big girl. If i still cared about lap times i'd stick a good 250 engine in mine, i am/was always around 5 secs a lap quicker on a RM250Z versus RM465z and faster still on a '85 kx250!  500s are fun though and i am GLAD i got to ride them against the big boys back then, at least when i got flogged it was by a fast guy!!!

yer Im the same ,the smaller it is the faster I ride it, probobably cos Im a short arse the RM500 donk is going into a sidecar the reason I chose the rm is they had the most low down and mid range out of the pack but are 7 to 10 hp down, am just doing a look see on who knows what in the preperation stakes (get in early) the most inportant things are suspension and handleing
ya havnt got a rear wheel havya

[Ktm181]

nope, looking for spare rear hub myself, ebay has em but more than i will pay for a spare!

With your 500 in a side car, CUBES will be the go surely?  I rode a 465 with a 3mm stroke increase 30 years ago, i still remember what it was like, it was also ported, WAY too much power, they ended up putting stock-ish barell back on it and it was nice then, but i was still quicker on a stock engine. GO the stroke route and try, it boosted the 465 bottom and mid up a fair amount and then maybe some porting after that.  Personally i dont reckon i would use a rm500 motor, parts are getting hard to find, i would go any of the other japs given the choice, trouble is i have Yellow in my blood, well yellow, green and now Maico!

If you hve your 500 head off, any chance of getting me a chamber volume? in ML??

yes and thats just for the postage have ya got any stroke info, referances or details (please) will just go stock for the start more important to get suspension and handleing set cos power is worth shit without it what would you guys go for on the a bit of porting, I think I got an idea but always want to hear others good results , yep me to I used to race em, work for em, and know em, so yellow it is, anyway its the thrill of the hunt getting bits ya wend da donk gets here will pull the head of for a mickey merv and give you the conbustion chambers cubic capacity in mm cube, cc, ml, but dont do fluid 0z

Shelpi,   Pipe & muffler, air box & jetting & you got the best 2 stroke engine ever !!!

on the suzukirm500 website is an interesting article on the major big ones for theyear across the dyno - the RM was so close to the CR it wasn't funny - certainly not 7-10 behind?

that is great to hear, because everyone was always saying how it was a pitty how they didnt produce the goods and were the last cab off the rank, but a fullfloater and the total torque charts suggest differant, anywho will still look at all and apraise  the situation when we get it rolling  all I know is good things can come from a mere 40hp if its done right

Tremendous motor,
By modern standards and documented on this forum Combustion Chamber has a few free HP
Dean Burt has done some of the hard work .
When I sold the last of the D's as old stock we supplied a 2nd head gasket to knock off the compression
It then became easy to start, as gentle as a PE400 but still with a decent hit.
