Loudelectronics - How is that 869cc Grizz?
...broken.
It is an awesome kit. However I paid a local v twin specialist to install it and they did not take the care to check and recheck. Head studs were not torqued to spec or they did not do a warm up and retorque, one or the other. Not that big of a deal. The big deal was that they did not put the bolt in that holds the line to the water pump or did not torque it right. Long and the short is that I drove it 38 miles with out any engine coolant.
So I am in the process of rebuilding my self to make sure it is done right. Should have done it my self from the get go but I do not have a shop and I can not bore the cases. Just working for some money and to pay down the loan I had to take out to have it built. Once I do that I will buy a new cylinder and get it running again.
The motor was actually completely fine to my surprise. The cylinder was un touched (did have yamalube in it), head was not twisted, piston rings were fine as well as everything else. The only damage that came of it was that it pulled the threads out of the cylinder. I have tried time serts to put the threads back in but the one that was really bad did not hold so the sert just popped out. So I have to toss a perfectly good cylinder on the account of just one thread which totally sucks. Only have 100k on the kit.
As far as performance goes, it will wheelie at 20 mph from stabbing the gas. There is no machine on the market that will touch it stock. A modded gade is close but it takes a lot of mods to do it. I am limited in my exhaust and need a larger diameter header to get full gains out of it.
Once I build it right, I have my full confidence in the reliability of this kit. After seeing the inside of my motor after that torture, as long as there is coolant this thing will haul the mail for a very long time. Very impressed. It also runs cooler then stock for some reason. May be more surface area for the coolant and bigger water jackets but I am not sure. Fuel milage is still really good. average about 18 on gravel roads, stock was 20. In the mud and trails it is less but that is a given.
