Thanks for the reply I think thats to complicated for me it will be easier to buy the dykes ring etc and have them machined to suit.

Can the cylinder be bored to take a different piston like a beta for example

Where did you get it from

Hi all which oko carb are people running on there 315r currently got the phbh 26cs which has seen better days. Thanks in advance

What ratio oil to fuel should used when there's roads and big banks then surely 80:1 is too little

Stripped down clutch casing today to inspect the plates i took the whole side casing off and the kick start spring didnt look right is was touching the outer basket so I removed and cleaned the kick start idler gear. The question is though when I put it back together do i have to put any tension in the spring buly winding it half a turn etc or do i just fit it straight in the hole as is? Pic for attention Thanks in advance

Ok thank you for your input I wouldn't know how ir where to start to get a head spacer made I did how ever put an additional base gasket of 1mm on the bike to no avail.

Increase base gasket size cleaned all carbon from head piston and exhaust carb is jetted to spec in manual running out of things to do

Have you found any cure

Has anyone used redex 0-60 octane booster in a 2 stroke to cure pinking?

Can anyone tell me what size pistons you can buy for a 250cc beta rev3 i know that a size D is 72.481 but what are the others also i need to know the gudgeon pin bore aswell does any one have a copy of the technical data page out of the owners manual. Thanks in advance

Thanks Thanks it currently has a 120 main 46 upper 46 lower needle clip is correct yeah thanks big help. Will order a new main straight away

No I haven't set the squish don't know what is meant to be? What difference will altering the port timing make? Where could I get the 1mm head spacer? Would a thicker base gasket give the same effect currently got a .5mm base gasket and pinking issues. What's driving me crazy

What is the standard jetting for the early 315 '97-'99 PHBH 26CS CARB? Only manual I can get is 2002 which has the newer carb
