Drz 400 Cylinder head on 450 fse
Hi has anyone else fitted a drz head on 450fse?
Mine destroyed the original head. ?Snapped valve?. So I fitted a drz head. The bike was originally hard to start from cold ?2003? model but ok when hot. Now it?s the opposite.i suspect the compression is to high for the starter/ battery as it will start with jump leads, no chance on kick start. Has anyone else done this conversion or had these starting issues? Thanks for any info. |
Make sure the compression release is working.
Sounds like it is sticking. |
The auto decompressor seems to be working.its action is fine when stripped and appears to work when rebuilt. It?s very awkward to inspect when rebuilt.
I have fitted hot cams but can?t see why they could effect the decompressor. Seems like the starter and battery are lazy. A previous owner fitted a later flywheel cover with different starter gears to try and solve starting issues I believe. Are the starters supposed to turn quite fast? As mine is relatively slow even when cold. If it doesn?t fire in first 3/4 attempts then the battery has not enough power but jump it and it fires straight up. |
