  1. Bahman, results from the test look good. I'd recommend putting a few miles on it and see what issues surface. I wouldn't try and clean out the intake butterfly crud, you'll likely compromise the air seal that the residue is providing. Enjoy.
  2. Roger, thanks. I'll check out the national motorcycle museum. Jim
  3. Based on my research I suspect the answer is no but is there a source of heritage certificates for Triumph motorcycles? I'm thinking specifically of a 1979 Bonneville. Thanks for the advice.
  4. something of an interference fit but I managed to prise it out.
  5. Hello all. Is it possible to remove the roller bearing cone, cage and rollers from the diff head once the drive flange is removed? I suspect not but I thought I'd ask. Thx.
  6. 15+ years ago I had an engine rebuild and decided to 'improve' the head with new bronze valve guides. Well I just had the head rebuilt, with stock guides, because 2 or 3 of the bronze alloy guides had loosened and moved. No evidence that they's seized due to too little clearance, likely it happened because of differing thermal expansion coefficients over ~15 years. Bottom line - I'd stick with stock guides unless there's a pressing reason to change. Jim
  7. TRier, where are you located? Lots of good advice and expertise above. Having read the comments and given the OK pressure (108) at the MU I'm left wondering whether the issue is a partial blockage of the fuel flow from PRV to MU core. 3 causes come to mind: A partial blockage of the fuel line between the PRV and MU. Of has that line been cleaned out or replaced? Has the internal condition of the flexible fuel line entering the MU deteriorated and so, when fuel attempts to flow, the line limits flow? The MU likely has the small fuel filter where the primary fuel
  8. JohnC did you ever fit that 6:3:1 exhaust and reassess the power deliver of your motor? I recall reading a series of interesting posts of yours some years ago where you experimented with stock and TT1200(?) manifolds. Jim
  9. John, does your newman cam have a serial number or references embossed or engraved on the end? Newman offered a close to stock replacement for the TR5 PI cam and the end markings are referenced in the photo below. Jim
  10. I'd welcome advice on valve guides and length. I see that Rimmer offers two lengths of valve guides - 2.0625 and 2.25 inch. In what circumstances would the different lengths be used? I currently have bronze guides and I was stunned to find one of the guides was relatively loose. I suspect I should replace all guides with steel and go back to a stock config. Thanks for the advice.
  11. I noticed that the TR6 - https://www.carandclassic.co.uk/car/C1246401 - has some form of aluminium or grey plastic shroud around the distributor cap. Was that a common factory or aftermarket fitment? Don't recall seeing one before, (could be my failing memory...!). Jim

    Shock Absorber

    Any thoughts on how old these shocks might be? Recal-R 2548 shocks. Needless to say they're no longer on the vehicle.
  13. Peter, I called them a few minutes ago. All they could tell me is that its likely not reground, its probably chilled iron. They don't manufacturing the product, its supplied from a variety of source countries... Jim
  14. Thanks for all the feedback. Jim
  15. Folks, I have a CP camshaft with a TR5/early TR6 profile and its manufactured by County. I bought the cam several years ago but I haven't installed it yet. Before I do I'd like to hear from members who might have had direct experience running this County cam. Bottom line - I don't want to install a poor quality cam... The identifying markings on the end face of the cam is "TRI6/150BHP" and the lobe profiles match my old TR5 cam. Feedback appreciated. Jim
