Last year was having problems with carb on 315r, in the end had to replace it, at the time all i could get hold of was phbl from splat shop. made up some adaptors for the hoses as external diameter of carbs was smaller on the new carb. the bike has run ever since, however it runs a little lumpy, was wondering if anyone had done this before and how they setup the jets in the carb, any help welcome. thanks

I put a PHBL26 on my 97. The air filter hose and the inlet /reed valve housing are available for reasonable money. I bought mine from Pidcocks although I'm not sure if you can still buy from them or whether you have to go to Craigs Motorcycles

Jet wise I can't remember but I recall fitting the upgrade D47 needle,bike carburates perfectly.

If you search on the Mont forums for PHBL jets I'm sure they've been posted before.

I have an 04 and the stock jetting is:

Pilot: #35, could go to #38

Mixture screw: now 2 1/2 turns out

Needle: D34 & D37, has D37

Needle clip: stock 3^rd.

Throttle valve: #4.5 or #5.0, has 5.0

Main: #110

Starter: #60
