Gas Gas SM450 tips
Hello DRZDEMON,
In reading your posts, I noticed you have one main problem to fix, and the rest are nickel -dime items that may require you to do a little fine-tuning on the bike. 1. Slow start problem. It helps to adopt a proper starting procedure for the 450 4T. I have a demo model in my shop that will start after 2 pistons pass over TDC every time. If you give me a call, I'll be happy to explain it to you, but I don't the time to type it all out now. Also, you need to use this spark plug: NGK CR7EX1 Iridum. The pre-set gap should be correct, check it and also do a plug check after installation to see if it the mixture looks right, which it usually does. 2. Jerking at the top of each gear: This bike does not have usable 2-mappings like the 2-stroke. Disconnect the wire under the seat to get the different mapping. Test it and see how you like it. Feel free to call me for more in-depth discussion. - Jack J&J Racing (Gas Gas Dealer) 251-649-6966 Last edited by Master Chief; 12-20-2006 at 07:20 AM. Reason: typo |
