A little different than the stock OEM jet, works!

Paul in CA

Comments On May 22, 2014:I used this in my Kymco Grandvista (aka Grand Dink) 250cc scooter with the stock Keihin CVK30 carb. Works great. I have a stock exhaust and air filter. The problem was the carb got clogged from sitting and I cleaned it several times but there was still a small off idle hesitation. I cured that with #48 pilot jet. Stock was #38. I ordered a variety of sizes from #42 to #58 and that worked best.

Cheaper alternative

Gustavo in TX – Machine this part was bought for: 2000 HONDA CR250R

Comments On Aug 28, 2013:I purchased this idle jet as a replacement for a larger one that was running too rich... at a fraction of the cost of the "OEM" one. It installed great and is working as it should.

TRAVIS in NV – Machine this part was bought for: 2005 YAMAHA YFZ 450

Comments On Jan 11, 2013:Cannot beat the quality of a Keihin Jet. The prices on here can not be beat either! It is far cheaper to get a handful of these jets rather than running the the local shop and paying premium for the exact same product.

Great quality jets

Alan in CA

Comments On May 10, 2011:They seem to flow very close to factory Keihen jets. I took out a Keihen jet and installed one of these. No change, engine ran the same. Jet changes I made brought engine right in and I felt every change. I could'nt ask for more. Great jets and cheap too.
