(Q) Hi everyone,

 

Was wondering if anyone could help me out in this problem which i'm facing. My coolant in my main radiator drops down preety fast.However, when i open it up to refill,There's built up pressure in the radiator which causes the coolant to move over to the coolant spare tank.What could be the probable cause? anyone?

Handling can be many things. I would replace the cone bearing, service the front fork, service the rear shock, check for warped rims, check if the tires are properly inflated.

Radiator clogged by rust or thermostat jammed.

Not necessary...but if you do carry extra load..can do.

Check ur tyre pressure and for uneven wear usage...but likely ur set of wheel bearings are gone.

i also got cold start problem in the morning, after warmed, back to normal. but one of the experienced rider told me is EO too thick (15W50) so the oil more difficult to heat up.. BTW how is the carb related to cold start? isit too lean in petrol or air?? i m using knn air fliter

 

I faced a similar problem and rectified it already... it was water seeped into the carburettor.. simple carb servicing and my throttle is back to normal

(QnA) On the contrary, my front wheel bearings last only 4 months. I still not sure how to stop water from fouling the bearings from the inside. I've checked the rim for rupture but can't find any. For the rear so far check out fine after 6 months of usage.

I also have this problem, but it only happens to me during a morning cold start. After warm up, then its back to normal. Experienced riders told me its something due to the carb tuning.

 

I dun hav this problem but the other way... my bike hard to start when its fully warmed up, cold start wise very easy... lolx..

Im having d same.. But i wun label it as a problem tho as i feel wen the ngine is warmed, d fuel tends to evaporate faster instead of reaching the carb...

When cleaning and lubing your chains how do you lift the rear of your bikes? I want to get a rear stand but the swingarms don't have anywhere to mount those small plastic pickups.

Guys, is it me, the weather or my bike? Its getting hotter ley. my calves can actually perspire after a ride on the e-way from clementi to tuas.

 

Any good recommendations for coolant or...do I have to do something else?

[ifourdesign]
