![]() Remove the four allen screws each from the exhaust and inlet rocker bearing covers. Remove rocker cover bolts and mark them, because they are all different and you wouldn’t want to waste your time thinking where one belongs etc. Remove your exhaust header pipe + silencer combo ![]() For a detailed procedure on the tank removal, you can refer to singh5g’s video. For the tank removal, remember to disconnect the fuel pump and low fuel sensor connectors first. Remove your seat (if it will interfere with your work), along with your fuel tank. Before you start any job, just admire your bike and realise that you’ll be back on it soon. It all starts off as an idea, and you don’t stop till it is done. A basic approach to the installation of the decomp is as follows (Assumption is that you have a nice basic set of tools for the removal of the cylinder head, which includes your wrenches/spanner/torque wrench set, allen keys etc.) Ebay link - Quick walkthroughīecause I’ve never done any engine work, and as I didn’t have the right tools for this, I had to take the cylinder head to the local bike shop to get the threaded hole done (Approx. It’s the one with 10mm thread and 1mm pitch, smaller than your RE key. It arrived within a couple of weeks as I’m in Australia. I bought the manual decompressor off E-bay from the US. With the push-button type decomp, if you don't want it to disengage automatically, you can just pull the pin back up after positioning your piston just past TDC. Also, the push button type will only make kick starting easier, it won’t be a good idea to try to turn off the engine with it as the hot exhaust gases will probably burn your finger and be harmful to the tank! But if you can get one done to vent to the exhaust port, you can use it to shut down the engine whilst causing minimal impact on the starter/sprag during kick-back. Only professionals with enough experience will be able to do it. The latter will require more head work and I don’t think any machinist can do it perfectly. This requires minimal head work as compared to the older cast iron type decompressors, which vent through the exhaust port. On most of our export models, this side is blank, with a nice circular template.īased on ace.cafe’s suggestion, the decompressor one can get (to vent to atmosphere directly) is the Harley push-button type. Otherwise, what we have to do is: Get a threaded hole done where the second spark plug is usually supposed to be. If you have this setup already, it might be easier to get the manual decompressor installed. With many thanks to ace.cafe and gashousegorilla’s (GHG) suggestion, a manual decompressor can be installed where the second spark plug goes in the Indian domestic market for the UCE. You can refer to the following topic, in which I document the removal of the automatic decompressor: Everything has been fine till now for them.įor the installation to be successful, obviously you’ll need to remove the auto decomp that comes with these bikes. Steve Thackery and a couple more members have also removed their bike’s auto decomp, and primarily use e-start. 2500km and there have been no issues till date. However, I’ve had the auto decomp removed for approx. ![]() The possible downside to not having the auto decomp is that when the engine is shut off, there is a risk of the piston going backwards and ruining the sprag. Harley riders have these on their bikes for making starting easier and saving their batteries + sprag. This is because the manual decomp releases more compression (as compared to factory auto) and disengages automatically as well. Yes, the e-start is better off with this type of decomp as compared to the auto decomp. Will you be able to use the electric start? Was the manual decompressor worth the trouble?Ī big yes! Please refer to this video for the decomp in action: So before I go further and make you read all this stuff, I’ll summarise: I had wanted this for a long time, as the auto decomp wasn’t enough for me. Hope you’re all well and enjoying the end of 2015 This topic is about the installation of a manual decompressor in a UCE Enfield.
