Well after a very long wait, the Tec cam was available.
Last weekend I decided to fit it.
Firstly the cam was lets say is a bit cheap looking, still rough casting marks own the larger diameter. Although not an issue still showed where the machine couldn't remove material waste due to the lack of it!
Fitting the pin, done by covering up the cam to protect it, making a 5mm thick plate drilled to take the pin so that it had good alignment. Once that was done the removal of the old cam was completed.
I also checked out the holes in the cam for loose swarf, yes there were some and blew them out with my air gun.
A word of warning, when the cam cog , bolt and plate was unbolted, I kept a magnet close by just in case the anything slipped and the magnet would get it.
What surprised me was when the locking plate was removed, the alignment pin from the gear shot out and stuck to the magnet. Bit on the loose side!!!!
A bit that did annoy me was when I put the new cam in was upon rotating the engine I noticed there was a small amount of oily swarf picked up in a couple of the holes. I forgot to check the holes for sharp edges!
They had scraped the bearing surface, not a lot but enough to piss me of as I should have looked, or the seller should have checked before sending!
The cam lobe holes were deburred but the journal faces were not.
So I did the best I could in situ.
Another problem was as the locking plate was returned , I noticed the pin was too long resulting in having the plate bow around it.
Close the lid and crack on, set the tappets and rotated the engine by hand as in the You Tube instructions, then fired her up and out for a long ride.
Impressions are after 150 miles , a spritely engine but nothing to write home about. Not sure it was worth the money and the fuss of doing the job. The sealer if your interested is about £9 for a tiny 50ml worth, I saw £40 for the larger one but I'm sure any high temp sealer would have done !
I do on the other hand think the MPG was a lot better but I am running under 4000 revs.
In the lower revs , pulling away the bike gets bogged down then starts to pull. I have the smaller front sprocket, a free flowing exhaust, the DNA filter and alloy front clamp around with drilled holes in the side panel , iridium plug also a booster plug. Short of getting the free flowing down pipe I'm sure I've covered all areas to make the engine breath.
I contacted the Tec company and they weren't too worried about the bearing surfaces getting marked by the drill holes stating they never had any complaints and all should be OK. In the video however it is stated never get any marks on the bearing surfaces!
Shame they don't guarantee their products for this only if it broke, then it would be argued of the installers confidence and professionalism in the trade!
Overall, I was going to buy the cam for my Triumph, after this I'm not .
Now I know that a lot of folks are going to say that their bike is a revelation with this cam and I will complete the running in for 300 miles then see if its better.
My mate has a cam to go in his bike and on our ride out, I'm sure his bike has a lot more power than mine standard but we will see , at least he is more the wiser through my experience fitting one.
