      2stroke mx classics nice one no prob mate I find it hard to understand on most stuff you know how to explain it. I had a nice black 2005 supermoto dtre last year but someone nicked it I was proper gutted still am and that’s why I’m doing this engine because it’s from when I had my bike as a spare

      Check powervalve cables are on right m8 there's a long and short one the may have got muddled, best way to check if powervalve related is disconnect servo and open valve to full and see how it runs

    • @2strokemxclassics
      @2strokemxclassics  3 года назад

      Hi It depends tbh ebay have some parts, fowlers UK sell many new parts. some parts are rare for your 2000 (wiring harness, cdi unit, left switches, plastics)which aren't made now but there's a couple of Chinese places that sell parts and there's a place in Portugal that does OK plastics, I have them on my white one on here apart from the rad shrouds as there a difrent shape too the originals. Bikerpartsshop is one and Ali express is another hope this helps

    • @2strokemxclassics
      @2strokemxclassics  3 года назад +1

      I'm on insta m8 if your on there send is some pics, a like them better pinned I've had them like that since 1991 tho so am used to them pinned. I like the powerband to kick in, there's a test drive vid av got on the ellecy start ya can see the acceleration, it's just personal choice some say pinned better some say working is better but the thing with working ones wen you give it some hammer the valve opens but then when u let off the revs the valve rotates back towards the piston, say u got a 57.5 piston in on a normal powervalve when that bore wears down the powervalve will be able to clip the piston, say your in 6th gear wide open the valve will be fully open missing the piston, wen u let off an the bore finally wears that powervalve can rotate back and hit the piston

    Great vid thanks , I may have missed it, but what was causing the slap, and the servo to run the wrong way. cheers

    • @2strokemxclassics
      @2strokemxclassics  3 года назад

      Hi thanks for watching, the Piston was to small he bought the wrong size and whacked it in, this was causing the slap, I'm sure he put a 56mm piston into a bore need in a 57mm piston. the powervalve wen bikes start moving spins the correct way av had a few that spin differently but all work the same wen moving👌

      No probs m8 I've had them with powervalves that lock and only go one way and then wen cables are took off the servo motor just spins constantly wen turn key and its been the cdi on 97-2003 bikes, might be cdi related if not the servo motor m8
