October 1, 200619 yr I rode my 325 beamish in the last round of the Euro cup yesterday. Quite fun but it is very "tired" to coin a phrase. That means, no poke! I now have a used std barrel with slight scoring and a new 0,25mm oversize piston (Thanks Robin!) Just need to visit the boring shop! Now my question: The barrel has a ca. 6mm hole drilled in it about 10mm above the exhaust port windows. Is this normal? Constructive answers only please Greeves!

October 2, 200619 yr The exhaust port is known as a 'bridged port' the bridge it's there to stop the ring popping into the exhaust port and breaking. the small round port to which you refer is a puffer port, it's used as a precursor, to get the exhaust gases moving in the right direction, ie up the exhaust pipe. Wether or not this works, either at low revs or high revs, in my opinion is debateable, I personally would tap the hole, with nice coarse threaded tap and put a loctited grub screw in it, I would try it with and then without a grub screw, see if there's any difference (you would only need to remove the exhaust to get the grub screw in or out) Your Beamish is probably running OK, if your used to riding a FANTIC then the Beamish is bound to feel sluggish, steer slow, have bad brakes, and feel bulky and heavy.
October 5, 200619 yr No this hole is not standard. It will advance the exhaust opening by a massive amount. I am amazed it ran well enough to ride, shouldnt have pulled at all. Use araldite in the hole not a grub screw as this is hard metal and could always come out.
October 6, 200619 yr Author So we have two opinions, std or not? I still have the 370 barrel on the bike at the mo and that is CRAAAAP! I will strip and check that to see if the hole ois there also. Lee
October 6, 200619 yr I am just a mortal and as such, i bow to those people who are my betters, those people who have proved there worth, those people who put there money where there mouth is. Who knows , who is behind the key board, could be an eleven year old schoolboy or a 60 year old Trials Rider, who has come 8th in the British Experts with a BA hons, Inst mech eng, who is recovering from major surgery and decided to expel some vision and a little humour or maybe just a Bloater with fallen footrests.
March 27, 200719 yr Sorry to drag up an old topic, but i can confirm that the RL325 HAS this hole in the exhaust port. S_M.
