The GSX-R750 GR71 definitely ranks high on the list of difficult idle adjustments.
Extended using a long idle screw for TMR. <\/a><\/p>\n\n\n\n\n\n\n\n

I’m torn on how much preload to apply to the spring… using the subtraction method…
Around 7 mm felt good when turning.

By the way, it’s M5-P0.5.
Kyohin has the same pitch too, so you might find something even more interesting if you search.

This time I used the TMR version, so it’s shorter by one carburetor length. However, considering availability and price balance, I chose this one.
I looked at various OEM parts too, but they were over 4,000 yen and I couldn’t tell if the dimensions would work\u2014that was the bottleneck. <\/p>\n\n\n\n

The plan is to spot-weld an ultra-low-head bolt to the band and fix it here. <\/p>\n\n\n\n

A bit of a niche upward angle. Rest assured, the foot doesn’t hit it either. <\/p>\n\n\n\n

The bolts arrived and I finally got the sync dialed in. <\/p>\n\n\n\n

Terminal covers are incredibly important. Without one, the risk of fire increases dramatically, so please do a quick check.
I used to love Honda OEM ones, but… actually these are discontinued too… seriously? That’s a bummer…
Next is a test ride and we’re done! (*^-^*) <\/p>\n","protected":false},"excerpt":{"rendered":"
