Hard To Start Running Rough Rev3

Featured Replies

My rev 250 has been causing me unwanted headaches. The last couple of times out I have had a hell of a job getting it started from cold. When it dose start it coughs and pops like a good un. The plug has been oiled up when removed. I am using a mix of 100 cc to 5L is this too rich ? When I replace the plug with a new one it seems to do the trick for a short while then its back to square one . My main concern is when the bike is ticking over it pops constantly unlike other rev 3s Ive listened too...... Any ideas ? :D

p.s I have done the carb mods on r2w ,s site

100cl to 5L is 50:1 which is very rich. Try and 80:1 mix and see how it goes (I've heard of people running up to 100:1 with fully synthetic oil but I don't think I'd try it!)

75:1 is a good ratio which is 67ml of oil too 5 litres but if your like me and not that anal over the measurement anywhere between 60 and 75ml of oil per 5 litres is good

My 04 did that for about 15 minutes then the stator packed in...... Then five trials later the new stator did the same.

My 06 rev3 is a complete b--tard to start when cold takes about 20 kicks then

it fires up likes it flooded I HAVE ALSO DONE CARB DRILLING MODS and keep trying spark plugs and i run at a mix of 70.1 any one else havin same bother!

What a shower.....

Bit of choke, ONE kick, on 70:1 with Silky 2t.....piece of pi$$...though not in with the petrol obviously.

Seriously when I got it I put a new plug in and blew through the carb before I kicked it over cos the guy I got it from had problems too. ....maybe it's weight behind the kick.... :D

like the new avatar Barry, (ps she won't let me buy superflous spares........sorry mate)

Edited by Slapshot 3

Belive me theres plenty of weight behind kick my 97 techno went ever 2nd or 3rd kick and that had plenty of compression as i rebuilt engine

Comming from kieth used to be a tech with lampkins 70:1 fully synthetic and 50:1 if running it on semi synthetic

Was that aimed at me? if so I get the avatar bit but not the spares?

That might be because it is (flooded). I had exactly the same problem on my old bike and tried everything to cure it (carb, electrics etc. etc.) to no avail. Then, when I took the engine out to be rebuilt I noticed fuel dripping constantly dripping from the hose, even with the fuel tap off. A seal inside the tap was buggered... you can see where this is going. One quick call to Lampkins to order a new tap and the problem was sorted!

yup,

pm'd you about the hub last week, she found out and I got grief....again!!

Once mine is started its fine. starts first kick just a t--t when its cold and been stood for a while also i use repsol oil?

Mine started 1st kick last week after being stood for over 3 months! I use 75ml of 'PJ1 Silverfire' oil per 5 litres of ordinary (stale?) unleaded petrol.

Turn fuel tap on, choke on, one full turn of the throttle and kick it with a smidge of open throttle :D

Thats how i was told to start it kinell but its not having it. Had no problem with my old techno!
