Cruisers / carburetor Change
« on: January 26, 2012, 01:11:03 PM »
Hi,  I have a 2009 Zongshen ZS125 { the same bike as the Lexmoto Arizona with different badges) which has covered 1600Kms which has a problem, namely;

Bike starts and runs ok and will happily top 50mph, but at large throttle openings ie 5/8 to full the bike does not rev cleanly and feels as though it has a miss-fire or a flat spot a bit like fuel starvation, the bike will accelerate up to quite high revs ie 55 to 60 in 5th. It has had this problem since I bought it last year

Before I start buying parts to change like cdi or ht coil I was thinking about a carburetor change possibly one from a cg125, does any one know if it will fit?
Has anyone had a similar problem?
I dont just want to throw money at it and take pot luck.  It has a new Ngk plug and cap fitted.

Thanks. Blakey

Hi,
just a post to introduce myself, I am retired, and I have bought second hand ZongshenZS 125-30  2008 with just over 1000 Km on it. The bike is MOT'd and on sorn.

I also have a 1999 Suzuki GZ 125 and I will insure both bikes on a multi-bike policy when the Suzuki insurance runs out in mid September.

I have had a brief ride of 12km on the Zongshen and all seemed O.K. but it has a missfire at highish revs (top third of rev range) under load. I have checked the coil resistance and it seems O.K. with readings of  LT to earth 1.2 omhs and ht to earth of 4.2kohms (about the same as aHonda C90). I do not have the figures for the 6 terminals on the CDI unit so if anyone has them I would be obliged if they could post them so that I can check if  the CDI's O.K.

My next ride on it will be in September when I can check out the miss fire further.

Tnx for reading,  :)
