I was told by my brother that it dynoed 397hp. I have no paper work of any kind that would verify that. Also, I just have no paper work at all. Just a bill of sale. VIN search shows it was never titled in Texas, only NC in 2003, SC also in 2003 and in Florida in 2004. One of the pics shows a texas tag from 2016. Tim had several Vmax's but this was his baby. So now starts the process of getting it titled. The engine case has the first two digits missing missing to make room for the chain and spocket. What's left is T-005206 which apparently is not an 86 engine. Anyone got any clues?
Do you think he might have any records on what all he did on this engine? The first two digits have been machined off to make room for the chain and sprocket. What's left is T-005206 which from my limited research is not an 86 engine. And by the way, since your in Derby is the beach house still open and would you by chance know Mike Mockry of Mockry Machine?
Thanks for the reply. I'm in Lincoln and I have the Bike in Omaha so I'll get up there next week and take a look. Robertson Cycle is rebuilding the engine.
I'm glad our world-recognized authority weighed-in on this. I think you could swap-out the first digit '3' for a '1' and still be optimistic. That would make it 197 RWHP which is almost 100 HP above your stock engine's RWHP which should be about 110. The factory 145 HP for the USA models is an 'at the crankshaft' reading. From reading all the bike magazines over the years, the highest RWHP reading I recall is 119 RWHP. The factories are known to assemble from 'best tolerances', bikes which are provided to the motorcycling press for testing. Also, another practice manufacturers use is to give the first year's bike a 'hot' set of cams to generate an impressive HP # for the magazines (now, the internet) to 'ooh' and to 'ahh' over. Yamaha did just that with the same-period FZR1000 'Genesis' engine, 5 valves/cylinder. The first year, it exceeded the VMax RWHP by a bit, but then, It weighed 100 lbs less, and had much-better aerodynamics, so of course its top-end was impressive for the day. It made 122 RWHP. That was in 1987, but for the 1988 model, they put in a set of cams which produced much-less RWHP but which had a much-stronger midrange. That made it a better ride, as that's where you do most of your street-riding.
Please clarify what is needed on the rebuild.
The R1 has been my passion since the first year 1998. I’ve been looking for a clean 98 for a long time. I missed the perfect one about 5 years ago it had 3,000 original owner miles on it I did however get his showroom mint 04 R1 with 713 miles on it. I’ve made the 04 special and it’s a keeper. I so love the 04-06 which was also the lightest generation to date. It and my 09 vmax are my keepers.
I’m curious what is wrong with the engine?
It was parked about 3 years ago with a blown head gasket.
It's supposed to just be a blown head gasket.
Wow. That would be good news. Several years ago he laid it on it's side leaving someones house. I think that it was shortly after that that he thought he had a blown head gasket. He drained the radiator and I think he said there was no anti freeze in the oil. I think he may have drained the oil too. The bike has sat since then as that's when he got sick. The plastic shroud around the radiator and the front fender got damaged when he put it on it's side so maybe that caused it's problems. I'm not sure what it was doing that made him think he had blown head gaskets.
Clean it up, add fresh fluids and I bet you're good to go (maybe replacing a radiator)
