pschrauber Posted March 14, 2012 Report Share Posted March 14, 2012 In the end o the 70's when I started with trials as a young teenager. Some riders using bikes like Montesa and Bultaco, (the SWM had a Deco as standard), had them fittig I because they make starting easier and you could use the deco as brake too when going down steep downhill. I believe it was more a fashion then really something extremly useful, (a deco does make starting easier for sure, also today). art Quote Link to comment Share on other sites More sharing options...
naichuff Posted March 14, 2012 Report Share Posted March 14, 2012 I had one fitted to an early 325 The head has to be machined for another 14mm plug hole there is advantages dropping down long hills but when released the engine fires up with a surge using up the unburnt fuel and can put you off balance The can also get dirt on the seat and stick open Plus the head gets fuel and oil sprayed over it Quote Link to comment Share on other sites More sharing options...

keychange Posted March 15, 2012 Report Share Posted March 15, 2012 It takes a lot of stress out of the starting gear - which on my 247 is not easily replaced Quote Link to comment Share on other sites More sharing options...
