I have for years fancied a HPN and did infact have my chassis booked in for a build at HPN - but due to an injury and loss of earnings had to cancel at the last moment. Fast forward a year to now and back on track for the project - I have tried to re contact HPN several times by phone, letter and e mail. I have been met with no reply. My new course of action is to build the HPN replica myself using contacts and local fabricators. I am using not my own gs chassis but a spare 247 r80st chassis for the build - The Chassis is now bead blasted and is now in the hands to be fabricated into a HPN replica for a tiny amount of the cost of the price charged by HPN (getting good mates rates on the job) by two good friends who run a chassis and fabricating workshop. Colin a genius in engineering and with years of knowledge of motorcycle building, chassis fabrication and a workshop with frame jigs, etc is behind the scenes on the build, whilst Rob is taking the project lead , A welder and fabricator, with experience in several environments from lorry fabrication and also military armoured vehicles (He is now a lecturer in welding at Newcastle college) and has also had till recently a fabrication workshop building racing quads along with various construction projects from kit cars to lorry conversions together they are undertaking the work of the Chassis. The Chassis has been checked for straightness and is currently having the various plates made up before being checked for fit then tacked into place for the frame strengthening, the frame will then be reset in the jig before welding some minor deviation from the HPN concept will be included to customise the chassis totally for my own requirements. This way I can use neater and different components that suit my build rather than being stuck to a set format from HPN. The sub frame, rack and swing arm again will be built up at Rob and Colins workshop. Once all built the frame, sub frame and swingarm will be de stressed and checked for trueness prior to going for powder coating. However the basic build principals are the same - twin shock rear end with specific built wilbers piggy backed shocks, Complete original HPN white power front end -sourced from e bay germany for £600.00, needs a service and tidy up but otherwise fine. I am using HPN Tank and fairing as I already have these to hand. I need to have the rear driveshaft lengthened by 100mm and have found a few sources for friction welding but am looking at a few others presently. I am rebuilding a new wiring harness and simplifying the whole system as BMW harness is too complex for my needs. The Charging, ignition and lighting will be seperated into three distinct harnesses to make access easier and if ever needed the repair or replacement would be much simpler. Engine wise I am using at the moment my r80gs engine and gearbox both have been modified and completely rebuilt the engine has all new components so is virtually a new engine;- It has a lightened and balanced crank, Balanced con rods (balanced over entire length to each other, steel lined oil pump, 296 enduro camshaft with a bronze bushed bearing,1000cc piston upgrade (siebenrock), gas flowed and twin plugged cylinder heads,2 twin tower dyna coils, one piece rocker/valve gear, deep oil sump, nissan starter motor, K and N air filter, SGS high torque exhaust, Endurolast alternator and twin spark electronic ignition, heavy duty clutch. The gearbox has High top gear and lower first. The engine puts out about 65 bhp and has 73nm torque measured at the back wheel at 2000revs right through to 6000 revs so nice and flat. I may in the future source a 1000 motor and go to a 1070 but money blocks that route at the moment. I will try to add a few pictures this week of each stage of the chassis build from start until its finished.
