Title: Beamish 325 RL Silver motors
Post by: YUMASTEPSIDE on January 25, 2012, 09:19:03 am

Does anyone have any info on the Beamish 325 conversions on the early suzuki "silver" motors. Do they use standard barrels? Stroked crank? Are the pistons / rings still available?
  Any articles or info would be appreciated.

Lots of info,thanks.........but not much technical stuff.  ???
  I'm trying to find out how they turned a 250 into a 325? Does the 325 sleeve fit a standard early barrel, did they change the crank or rod ?

Hello, I am probally wrong but i havent seen or read about any silver engine 325 beamish bikes. The only 325s i have seen had the black engine which was supposed to have been made as a 325 .{ 250 black engines are fitted with an extra liner bringing them down to 250cc  and some differance on cyl. heads to get correct compression ratio} I think several people have converted a black engine 250 to a 325 by removing the liner , new piston & altering compression with machining or extra gaskets.
The black & silver engine 250s have same bore & stroke 70x64 .The 325 is 80x64 so only differance is bore size wouldnt think crank or con rod are any differant.
Anyway i expect you allready know all this , i think there is a thread on this subject  on the Trialscentral forum somewhere.
if i find any more info i will put it on here

From what I've read, the "silver" motors were the first of the RLs, basically an early TS motor,maybe '72 to '74.

Yes based on TS motor. I wonder why they made the RL exhaust port go the other side to the TS motor?
