Bought her 21 April 2016. The Yoshi is only a cone completely open with those stamped areas for minimal back pressure. It is VERY loud. The test ride with only a tach, hit approx 120mph according to neighbor bike speedo. Front piston dragged severely but not known at that time. Definitely has 100+ hp. Not that it can touch my 2002 ZX9R's 144HP, but impressive!
During operation thermostat and radiator hoses I have discovered the fact that the lower radiator is right on top of the oil filter. I am not going to remove the radiator every 6 weeks to change the filter. Hmmm.
You don't have to remove the lower radiator - just remove the mounting bolts and let it hang while you get at the filter. No problem.
I still remember my 1984 VF750F. It had a ton of little issues that drove me to distraction. For example, the manual says that you have to split the cases to replace a leaky clutch pushrod seal. WRONG! And that awful pneumatic shock. Ugh!
BUT there are relatively inexpensive fixes and expedient work-arounds for a lot of the issues. I may even have some parts lying around. Enjoy!.
EDIT: I see yours doesn't have the stock shock. Good.
At 500 to 700 miles per week, I rack up oil changes fast. Cars go up to 5k on oil. All my motorcycles get oil and filter close to 3k as practical.. I see what you mean about the bracket. Mine has 3 on the upper and one on lower 4 in fans so it is more fiddly. Probably delete the lower.
In the 8 months since I took the front calipers off for rebuild, I have lost or incorrectly installed the left TRAC arm. See the bushing in the caliper bolt is longer than the bushing in the TRAC hole of fork. Both bolts bottomed out with link still floppy in addition to not parallel.
Could also be that the axle is in from the wrong side... Axle, according the schematics goes in from the speedo side.. Nut/bushing should be on the right side of the bike.. Checked that ?? My VF is currently in storage. Could check and shoot some pics later this week..
I zoomed in on one of the pics. and this came out...
Although unknown cbr 17s with rotors and sprocket, stock front axle and brakes. Am following fsm for axle torque. Assured axle installed correctly. Right leg is torqued. Left TRAC leg controls width vs caliper mount to rotor clearance. Flange appears to go towards rotor. What are the other two items marked? Switched bushings and bolts torque down correctly now.
Front is 3 distinct spokes and deep offset wheel bearings. The braking rotors and rear sprocket part numbers all turned up nothing when searching. Apparantly all items discontinued... Or numbers stamped have to cross to something. All calipers and mounts are stock 1983 VF issue.
Thanks for the pics. The front rim, as Captain 80's noted, does appear to be a Dymag, lucky you! I'll start to look at CBR front rims to see what would work best.
You have a very interesting 83 Vf750F. I 'll look forward to further posts.
Front calipers fully rebuilt.. Broke the anti-dive bolt before 27 ft-lb could be attained. Now a helicoil is required to fix. Had visions of bleeding brakes and filling forks with oil and front end would be done. Ugh. Replaced all rubber in coolant hard lines but only ordered 1 of the orings for the covers under carbs. New coolant hoses, with in-line sender for my trail tech in upper hose.
Thermostat housing was corroded so ordered a great condition used one plus tail lense with harness and complete harness. My wiring harness had the wires for tail light cut out at least a foot back. Cleaning and inspecting the harness presently.
