good evening passengers, this is your captain speaking. up ahead in the stratosphere is a USA-made, NASA inspired water cooled head specifically made for the puch 45mm piston port treat kit!!
buckle up amigo, time to blastoff to the future!!!
features:
- one piece design, 100% sealed against seam leaks
- bolt on fittings with perfectly matching o-rings on each side
- fittings have 360 free range of motion, ready to be bolted down to your desired angle! comes with 2 bolts.
- uses normal bhs plugs
- this head is NON o-ring style. just normal style! perfectly matched to the puch 70cc piston port kit
you WILL have to use LONGER cylinder studs. gotta go from m6 x 106mm (which is stock) to around 126mm or longer! basically you need 20mm more than the stock studs.
alternately, you could use the minarelli m6 x 136mm studs and some m6 spacers to fill in the extra stud length.
the head itself has a 113mm diameter. bolt holes are made for m6, but actually accommodate m7 as well, although it is a very tight fit. might be for the better, though, if desired.
fittings are 16mm OD, 15mm ID.
Please note when installing the fittings you should position the fitting in the direction you desire it to go and then tighten down the bolt. If you attempt to tighten down the fitting and then turn it the seal will be twisted and will possibly not seal. Make sure you follow these instructions carefully!!!!
here is a replacement head o-ring!
head diameter is about 114mm and about 28.5mm wide.
bolt hole pattern is about 44mm x 44mm. do NOT attempt to widen holes, it will go through the surface! most likely like 99%
water cooled isnt for everyone. make sure you have enough experience before you DIVE in (hahaha i crack myself up)
anyway, this thing is seriously sick. just about as flawless as it can get. MIGHT have a few tiny little pits in one of the fins, but basically perfecto!
enjoy your journey into uncharted territories. just make sure one day, you can amaze your friends and tell them:
"IT RUN ON WATER!!"
