Question: How many hours till its time to rebuild your top end?
Answer: Its not so much how many hours till it is time but more along the line of how many PSI of compression its running at. The average compression on a newly rebuilt engine is around 140 PSI. If you run a compression test and its under 115 PSI then its time for a rebuild and once past 110 or so - you start to really mess up your cylinder.
Question: Whats the correct tension of my chain?
Answer: You want to be able to grab the top of the chain in the middle and move it down a half of an inch, and up a half of an inch for a total of 1 inch movement. This is the desired tension.
Question: Whats the stock jetting for the Blaster?
Answer:
Mixture screw 1 ½ turns out
Jet needle clip 2nd groove
Main jet 230
Question: What do I set the gap to on my spark plug?
Answer: Plug gap 0.7-0.8mm .028-.032in
Question: To check if my jetting is right, how do I do a proper plug chop?
Answer:
Warm up the bike to normal operating temps.
Find an open stretch of road. Change the plug, you must use a new plug for each test. As quickly as possible (not letting the engine idle)...get it up to the highest gear achievable - wide open throttle - hold it there as long as possible (at least 20 seconds). While holding the throttle open, hit the kill switch and pull in the clutch at the same time. Make sure you do not let the engine idle or slow down or let off the throttle until it comes to a complete stop.
Now,
Pull the new plug and check the color.
Grayish tan = perfect
White = too lean
Dark brown or black = too rich
Question: Where do I place my reed spacer, before or after the reed cage?
Answer: Putting the spacer between the reeds and the engine moves the powerband lower to improve bottom end HP. the thicker it is the lower it will move the powerband.
Putting the spacer after the reeds and moving the manifold back moves the powerband higher and help to improve the mid through top end power. The farther back the manifold is the higher up it moves the power band.
More will be added to this section as I have the time, keep checking back for updates
