Stared at my R1 wishing weather would get better. Ive put 10 miles on it since I bought it :banghead:
Actually been really busy working on the WR450. I stripped out a bolt on the oil filter cover that screws into the clutch side cover for the case. I decided to replace the whole cover instead of heli coil it as I got the case in great condition off ebay for $22.00.
and with the slow going trails we tend to ride and the 90F + weather we see in summer ive had some times I have over heated so I figured why not upgrade the waterpump while im at it. Then since I have to drain coolant and I smashed a radiator, might as well replace that as well. Oh and a rock cracked a small hole on my ignition side case cover, so I JB welded that. Ive done it with friends bikes before and worked like a charm, so Ill give it a go and if it doesn't hold replace.
Ok so got plastics off, and here we are all stock. Radiator was tweaked before I got my Devol Radiator guards.

Removing Cover was pretty simple and straight forward. I was very pleased with as much and as hard as I ride the bike how it looked inside. Everything looks great, gear teeth look awesome.
Cover Removed
So the whole reason (mostly) that I did this was because of that bolt I stripped. The reason it stripped was when you remove the bolt for the oil filter cover, the excess oil from the filter area drains through that bolt hole back into the case to help keep oil changes clean. Well particles and metal bits from clutch ect.... gets caught in the threads of the hole and when you place the screw back in it can eat away at the threads. Found a great write up on this on ThumperTalk.com, and they recommended plugging the hole with a small bearing. Drill out hole slightly larger about half way through it, place in bearing and then punch it down to hold in place.
Its upside down pic but there it is. Holding very well and solid. Im not worried on it coming out.
Ok so hole plugged, time to tackle water pump.
Stock on left, Boyesen on right.
Great reports online of much cooler temps. Did a rebuild kit on it also so new bearings and seals since im in there. Got it all together. Looks pretty.
The rest was simple stuff. New Radiators go on, just replace where old ones were. Bought oversized again, its what I had before and I was fairly happy with them.
Had to modify a bit to fit devol rad covers, just cut off tabs for airscoops as I wont be running them anyways.
All back together and running perfectly. Ran great, just idled in garage but no leaks :woot: and all sounded normal. Hoping to get it out tomorrow and actually ride it and make sure its all holding up correctly.
